Simplifying 4x2 + 5x + -45 = 0 Reorder the terms: -45 + 5x + 4x2 = 0 Solving -45 + 5x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -11.25 + 1.25x + x2 = 0 Move the constant term to the right: Add '11.25' to each side of the equation. -11.25 + 1.25x + 11.25 + x2 = 0 + 11.25 Reorder the terms: -11.25 + 11.25 + 1.25x + x2 = 0 + 11.25 Combine like terms: -11.25 + 11.25 = 0.00 0.00 + 1.25x + x2 = 0 + 11.25 1.25x + x2 = 0 + 11.25 Combine like terms: 0 + 11.25 = 11.25 1.25x + x2 = 11.25 The x term is 1.25x. Take half its coefficient (0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. 1.25x + 0.390625 + x2 = 11.25 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = 11.25 + 0.390625 Combine like terms: 11.25 + 0.390625 = 11.640625 0.390625 + 1.25x + x2 = 11.640625 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = 11.640625 Calculate the square root of the right side: 3.411836016 Break this problem into two subproblems by setting (x + 0.625) equal to 3.411836016 and -3.411836016.Subproblem 1
x + 0.625 = 3.411836016 Simplifying x + 0.625 = 3.411836016 Reorder the terms: 0.625 + x = 3.411836016 Solving 0.625 + x = 3.411836016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.625' to each side of the equation. 0.625 + -0.625 + x = 3.411836016 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = 3.411836016 + -0.625 x = 3.411836016 + -0.625 Combine like terms: 3.411836016 + -0.625 = 2.786836016 x = 2.786836016 Simplifying x = 2.786836016Subproblem 2
x + 0.625 = -3.411836016 Simplifying x + 0.625 = -3.411836016 Reorder the terms: 0.625 + x = -3.411836016 Solving 0.625 + x = -3.411836016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.625' to each side of the equation. 0.625 + -0.625 + x = -3.411836016 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = -3.411836016 + -0.625 x = -3.411836016 + -0.625 Combine like terms: -3.411836016 + -0.625 = -4.036836016 x = -4.036836016 Simplifying x = -4.036836016Solution
